1 cup (2 sticks) unsalted butter
2 cups light brown sugar
2 teaspoons vanilla
2 cups all-purpose flour
1/2 t salt
2/3 cup chocolate chips
2/3 cup white chocolate chips
2/3 cup butterscotch chips
Preheat oven to 350. Spray a 9×13 pan with non-stick cooking spray. Set aside.
Melt the butter. Combine in a large mixing bowl with the brown sugar. Add the vanilla and the eggs and beat on medium speed until combined. Add the flour and mix until just combined. Add the chocolate chips, white chocolate chips, and butterscotch chips and mix until combined.
Transfer the batter to the prepared pan and bake for 20-30 minutes or until golden brown on top. Allow to cool completely before cutting into bars.
